A full color light emitting diode display (310) utilizes semiconductor light emitting diodes (313) to produce red light and organic light emitting diodes (312) to produce blue light. Green light is produced by either semiconductor light emitting diodes (313) or by organic light emitting diodes (331). An array of semiconductor light emitting diodes is formed on a semiconductor substrate (322) and an array of organic light emitting diodes is also formed on semiconductor substrate (322) adjacent to the array of semiconductor light emitting diodes. The array of organic light emitting diodes cooperates with the array of semiconductor light emitting diodes to form an array of multi-wavelength pixels of the full color light emitting diode display (310).
